Crest Audio, the first company to offer computer controlled amplification now raises the bar. With the introduction of the CKi series of amplifiers, Crest Audio has added many standard features that other manufactures either charge additional for or don’t offer at all.Whether your requirements are simple or extremely complex, CKi series amplification systems are perfect for permanent installations of any size. As with all Crest Audio amplifiers, reliability and sonic performance are the most important factors in the amplifiers design.

NxCobraNet Module :

The NxCobraNet module supports all NexSys control and monitoring functions as well as delivering two channels of CobraNet digital audio to the amplifier on one ethernet cable. Supported computer controlled NexSys functions include gain, sequential power, and real time load monitoring.Amplifier monitoring includes input and output level
(VU), DC protect, thermal protect, IGM, clip status, power state,AC mains, heatsink temperature, gain selection, ground lift status, and audio return.
The LED display allows easy in rack readout and monitoring of temperature, gain, AC voltage, IP address, amplifier ID, as well as CobraNet bundle and channel status.
Individual indicators display fault and mute status by channel as well as ethernet link and data indicators.
The NxCobraNet module requires no other additions to make it network ready.
The module has an RJ-45 ethernet connection that is made through a Category 5 compliant Neutrik EtherCon connector to ensure a secure connection.

NxDSP Module :

The Crest Audio NxDSP plug in board for NxCobraNet and NxEthernet performs various functions depending on which module it is used with.
NxCobraNet module: in addition to speaker processing the DSP installed in the NxCobraNet module provides 8 channels of CobraNet audio decoded to analog outputs on the back of the module.
